Abstract

An exchangeable ring filter element (3) hangs from a supporting head (1). It is fitted to the head with the aid of a jig while hanging plumb and is then secured by means of a rod (2) and sceew tightener (4). The novelty is that a number of temporary bayonet lock supports (7) are provided which are independent of the screw tightener (4), and that the uncompressed ring filter element (3) may be axially inserted and rotated into its correct position before being locked into place by the screw tightener (4). USE/ADVANTAGE - The jig facilitates accurate fitting of the filter insert. The jig enables the filter removal and replacement to be accomplished by a single person instead of two.

Description

Die Erfindung betrifft eine Montagehilfseinrichtung für ein an einem Filterkopf lotrecht hängend aus­ tauschbar befestigbares Ringfilterelement nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an assembly aid for one hanging vertically on a filter head exchangeable attachable ring filter element after Preamble of claim 1.

Bei derartig hängend befestigbaren Ringfilterelemen­ ten besteht ein Problem darin, das Ringfilterelement in aufgestecktem Zustand zu halten, bis die Haupt­ spannvorrichtung montiert und damit funktionsbereit ist. Dies gilt insbesondere für Fälle, in denen meh­ rere Ringfilter in Achsrichtung hintereinander liegen und lediglich durch eine an dem weitesten von dem Filterkopf abliegenden Filterelement angreifende Spannvorrichtung gespannt werden. Denn in diesen Fäl­ len müssen sämtliche Ringfilterelemente bis zur Mon­ tage der Spannvorrichtung gehalten werden. Da die Ringfilterelemente, insbesondere, wenn sie im Aus­ wechselzeitpunkt mit Schmutzpartikeln beladen sind, bei größeren Elementabmessungen relativ hohe Gewichte besitzen können, ist bei den bisherigen Ausführungs­ formen eine Montage durch eine einzige Person häufig nicht möglich. Es sind vielmehr zwei Personen erfor­ derlich, von denen eine die Filterelemente in der zum Spannen notwendigen Position hält, während die zweite Person die Spannvorrichtung aufsetzt und sodann das Spannen der Elemente vornimmt. In schmutzbeladenem Zustand können größere Filterelemente (Gewichte von weit über 10 kg besitzen.With such hanging attachable ring filter elements One problem is the ring filter element to keep in place until the main Clamping device installed and thus ready for use is. This applies in particular to cases in which more The ring filters are lying one behind the other in the axial direction and only by one at the furthest of that Filter head attacking filter element Clamping device to be clamped. Because in this fall len all ring filter elements up to Mon days of the jig are held. Since the Ring filter elements, especially when they are out are loaded with dirt particles, relatively large weights for larger element dimensions can own is in the previous execution often form an assembly by a single person not possible. Rather, two people are required derlich, one of which is the filter elements in the for Holding necessary position while holding the second Person puts on the jig and then that  Tensioning the elements. In dirt-laden Larger filter elements (weights of have well over 10 kg.

Hier eine Montagehilfe zu schaffen, die es insbeson­ dere ermöglicht, derartige Filterelemente mit nur ei­ ner Person mon- und demontieren zu können, ist das Problem, mit dem sich die Erfindung beschäftigt.Here to create an assembly aid, in particular which allows such filter elements with only egg Being able to assemble and disassemble a person is that Problem with which the invention is concerned.

Eine grundsätzliche Lösung dieses Problemes gibt das kennzeichnende Teil des Patentanspruchs 1 an.There is a basic solution to this problem characterizing part of claim 1.

Zweckmäßige Ausgestaltungen sind Gegenstand der Un­ teransprüche.Appropriate configurations are the subject of the Un claims.

Einzelheiten der erfindungsgemäßen Lösung nach den Haupt- und den Unteransprüchen werden nachstehend im Zusammenhang mit in der Zeichnung dargestellten Aus­ führungsbeispielen noch näher erläutert werden.Details of the solution according to the invention Main and subclaims are set out below in Relation to From shown in the drawing management examples are explained in more detail.

Fig. 5 einen Schnitt durch ein temporäres Hal­ temittel in Fig. 4 nach Linie V-V. Fig. 5 shows a section through a temporary Hal temittel in Fig. 4 along line VV.

An einem Filterkopf 1 ist lotrecht ausgerichtet eine Befestigungsstange 2 angebracht.A mounting rod 2 is attached to a filter head 1 in a vertically aligned manner.

Koaxial zu der Befestigungsstange 2 sind zwei in Rei­ he aneinanderliegende Ringfilterelemente 3 aufgezogen und über eine Spannvorrichtung 4 untereinander und dicht mit dem Filterkopf 1 verspannt. Die an der Be­ festigungsstange 2 angreifende Spannvorrichtung 4 be­ steht aus einer Spannmutter 5, die direkt an der Be­ festigungsstange 2 angreift und einer sich zwischen der Spannmutter 5 und dem Ringfilterelement 3 er­ streckenden Endscheibe 6.Coaxial to the mounting rod 2 , two ring filter elements 3 lying against each other in series are mounted and clamped to one another and tightly with the filter head 1 via a clamping device 4 . Be on the fastening rod 2 attacking clamping device 4 be consists of a clamping nut 5 , which directly engages the loading rod 2 Be and one between the clamping nut 5 and the ring filter element 3 he extending end plate 6th

Bei der Ausführung nach Fig. 1 ist lediglich das dem Filterkopf 1 nächstkommende Ringfilterelement 3 mit Hilfe eines temporären Haltemittels bis zur endgülti­ gen Verspannung fixierbar. Dieses temporäre Haltemit­ tel ist ein Bajonettverschluß 7.In the embodiment according to FIG. 1, only the ring filter element 3 closest to the filter head 1 can be fixed with the aid of a temporary holding means up to the final clamping. This temporary Haltemit tel is a bayonet lock 7 .

In dem vorliegenden Beispiel ist der Bajonettver­ schluß 7 wie folgt aufgebaut.In the present example, the bayonet lock 7 is constructed as follows.

Der an einem Filtergehäuse B montierte Filterkopf 1 besteht im wesentlichen aus einem Dreiarm mit einem Zentrum in der Achse der Befestigungsstange 2. An den Enden der einzelnen Arme 9 ist jeweils unter Durch­ dringung des Filtergehäuses 8 ein Zapfen 10 parallel zur Achse der Befestigungsstange 2 angebracht. Diese Zapfen 10 sind jeweils an ihrem von dem Filterkopf 1 abgewandten Enden mit einem radial überstehenden Kopf versehen. Auf diese Weise ist zwischen dem Kopf des Zapfens 10 und dem Filtergehäuse 8 ein sich parallel zur Achsrichtung der Befestigungsstange 2 erstrecken­ der Hinterschnitt vorhanden. In diese Hinterschnitte können Auskragungen 11 des Filterelementes 3, die an den dem Filterkopf 1 zugewandten Ende der Endscheibe des Ringfilterelementes 3 angeformt sind, durch Dre­ hen des Filterelementes 3 eingreifen. Dadurch kann ein Ringfilterelement 3 temporär in den Zapfen 10 ge­ halten werden. In axialer Richtung der Ringfilterele­ mente 3 müssen die Auskragungen 11 schmaler als die betreffenden Hinterschnitte an den Zapfen 10 sein, damit eine axiale Verschiebbarkeit zum Spannen des Ringfilterelementes 3 noch vorhanden ist. Das Einfüh­ ren der Auskragungen 11 in die Hinterschnitte an den Zapfen 10 erfolgt bajonettverschlußartig durch ein entsprechendes Verdrehen des Ringfilterelementes 3 nach dem Aufstecken auf die Befestigungsstange 2.The filter head 1 mounted on a filter housing B consists essentially of a three-arm with a center in the axis of the fastening rod 2 . At the ends of the individual arms 9 , a pin 10 is attached parallel to the axis of the mounting rod 2 under penetration of the filter housing 8 . These pins 10 are each provided at their ends facing away from the filter head 1 with a radially projecting head. In this way, the undercut is present between the head of the pin 10 and the filter housing 8 and extends parallel to the axial direction of the fastening rod 2 . In these undercuts projections 11 may be of the filter element 3, facing the head 1 the filter end of the end plate of the ring filter element are formed three through Dre hen the filter element 3 to intervene. This allows a ring filter element 3 to be temporarily held in the pin 10 ge. In the axial direction of the Ringfilterele elements 3 , the projections 11 must be narrower than the relevant undercuts on the pin 10 , so that an axial displacement for tensioning the ring filter element 3 is still available. The insertion of the projections 11 into the undercuts on the pins 10 is done in a bayonet-like manner by a corresponding rotation of the ring filter element 3 after plugging onto the fastening rod 2 .

Eine alternative Ausführung temporärer Haltemittel zeigen die Fig. 4 und 5.An alternative embodiment of temporary holding means is shown in FIGS . 4 and 5.

Bei dieser Ausführungsform können bei hintereinander­ geschalteten Ringfilterelementen 3 die einzelnen Ringfilterelemente jeweils auf einfache Weise für sich temporär gehalten werden. Die temporäre Halte­ rung er folgt bei dieser Ausführungsart an der Befe­ stigungsstange 2. Zu diesem Zweck ist die Befesti­ gungsstange 2 an den betreffenden Halterungsstellen mit umfangsmäßig gegenüberliegenden Nuten 12 verse­ hen. In diese Nuten 12 greifen Federn 13 eines Halte­ kreuzes 14 ein.In this embodiment, the ring filter elements 3 connected one behind the other can each be kept temporarily for themselves in a simple manner. The temporary holding tion takes place in this embodiment on the fastening rod 2 . For this purpose, the fastening supply rod 2 is hen at the relevant mounting points with circumferentially opposite grooves 12 verses. In these grooves 12 springs 13 of a holding cross 14 engage.

Das Haltekreuz 14 kann ein ausschließlich zu Montage­ zwecken dienendes loses Montagekreuz wie im Falle des dargestellten Haltekreuzes 14 sein.The holding cross 14 can be a loose mounting cross serving exclusively for assembly purposes, as in the case of the holding cross 14 shown .

Bei dem am weitesten von dem Filterkopf entfernt lie­ genden Ringfilterelement 3 können die in die Nuten 12 eingreifenden Federn 13 aber auch in die Endscheibe 15 des betreffenden Ringfilterelementes 3 integriert sein.In the most distant from the filter head lying ring filter element 3 , the springs 13 engaging in the grooves 12 can also be integrated into the end plate 15 of the ring filter element 3 in question.

Die Mon- und Demontage der Federn 13 in die Nuten 12 der Befestigungsstange 2 erfolgt durch Drehen des Haltekreuzes 14 bzw. der Endscheibe 15 um etwa 90 Winkelgrade. Wie bei der Ausführung mit dem Bajonett­ verschluß nach der Fig. 1 ist auch bei der Ausführung mit den Nuten 12 eine axiale Verschiebbarkeit der Fe­ dern 13 in den Nuten 12 erforderlich, um die Ringfil­ terlemente 3 ordnungsgemäß verspannen zu können.The assembly and disassembly of the springs 13 in the grooves 12 of the fastening rod 2 is carried out by rotating the retaining cross 14 or the end plate 15 by approximately 90 degrees. As in the embodiment with the bayonet lock according to FIG. 1, an axial displacement of the springs 13 in the grooves 12 is also required in the embodiment with the grooves 12 in order to properly clamp the Ringfil elements 3 .

Sowohl bei den Mitteln des Bajonettverschlusses 7 so­ wie bei dem Verschluß über die Federn 13 und Nuten 12 ist es möglich, die als Nut- und Federteile wirkenden Mittel an den Ringfilterelementen 3 einerseits und dem Filterkopf 1 bzw. der Befestigungsstange 2 ande­ rerseits funktionsmäßig gegeneinander zu vertauschen.Both with the means of the bayonet lock 7 and with the lock via the springs 13 and grooves 12 , it is possible that the means acting as tongue and groove parts on the ring filter elements 3 on the one hand and the filter head 1 or the fastening rod 2 on the other hand functionally against one another swap.
